Phylogenetics

Back

Uses DNA evidence to construct a diagram representative of the evolutionary relationships between organisms.

Front

Gene pool

Back

Consists of all genes, including all the different alleles, that are present in a population.

Front

Relative frequency

Back

The number of times that an allele/phenotype occurs in a population, compared with the number of times other alleles/phenotypes for the same gene occur.

Often expressed as a percentage

Part / Whole

Front

evolution

Back

any change in the relative frequency of alleles in a population.

Front

Hardy-Weinberg principle

Back

Allele frequencies in a population will remain constant unless one or more factors cause those frequencies to change.

Front

Five conditions are required to maintain genetic equilibrium from generation to generation:

Back

There must be random mating

The population must be very large

There can be no movement into or out of the population

There can be no mutations

There can be no natural selection
